SPECIFICATION forming part of Letters Patent No. 606,510, dated June 28, 1898. Application filed Debe'mbl 4, 1895. Renewed December 13, 1897. Serial No. 661,757. (No model.)

To all whom it may concern:

Be it known that I, ADELBERT E. BRONSON, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Steel Ranges; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will'enable others skilled in the art to which it appertains to make and use the same.

One object of my invention is to produce a cheap steel range of novel construction, a range which may be made in small sizes and with ovens of any desired size relative to the size of the tops.

Another object is to so construct and connect the component parts of a steel range that they maybe easily and quickly connected in the proper relation to one another or knocked down for convenience in shipment, and so also that the component parts will not buckle either when being connected together or later when they are expanded and contracted in use.

Theinvention consists in the construction and combination of parts hereinafter described, and pointed out definitely in the claims.

In the drawings, Figure 1 is a perspective View of my improved'range. Fig. 2 is a vertical sectional view on line 2 2 of Fig. 1. Fig. 3 is a vertical sectional view thereof on line 3 3 of Fig; 1. Fig. i is a horizontal sectional view on line 4. 4 of Fig. 1. Fig. 5 is a vertical sectional View on line 5 5 of Fig. 1.

Referring to the parts by letters, A represents the front; 13, the back; 0, the end at which the fire-pot is placed, and D the other end. These four sides may be made severally of single pieces cut into the desired shape, or theymaybe built up of several pieces, as desired. The upper parts a, b, c, and d of the sides, just above the top oven-plate, are

bent outward, as shown, and they may ex-' tend outward to any'desired distance,depending upon the size of top which is to be used. These outwardly-bent parts a, b, c, and d are preferably formed separately from the sides proper and are secured thereto by cup-joints K and bolts It. By cup-joint, here and elsewhere in the specification, is meant a joint formed by folding or bending the edge k of one of the parts tobe united back parallel to itself, so as to form a channel 7.2, into which the edge 70 of the other part enters and in which it may be secured by bolts k which specific construction, as above explained,may be seen at the lower right-hand corner of Fig. 2. Another form of cup-joint which may be employed is shown in the upper corners of the oven, as shown in Fig. 3, and in this construction the edges 7a 10 of both parts are bent or folded back into positions parallel to themselves, forming channels and the edge of each enters the channel in the other. In other cases-for example, at the right hand vertical joints of oven-plates with the sides, as shown in Fig. 4-the edge of one part is twice folded to form the channel 7c,into which the edge or edges of one or more of the other parts enter. In all cases bolts pass through holes in the folded-over edge or edges,in the parts of which the folded-over edges are portions, and in the parts which lie in the result ing channels. The bolt-holes are made some-. what larger than the bolts, wherefore, and because of the give and spring of the bent metal, the connected parts are susceptible of some relative movement. They are not therefore buckled when they are being connected nor when they expand and contract in use, neither do the scams or joints open during such expansion or contraction. rivets are used to unite lapped joints-and I believe the parts of prior steel ranges have always been connected in this manner-tho parts are frequently buckled when being connected and more frequently become buckled when the stove is being used.

The cup-joints above described, which are preferably used in my range whenever they can be, may be filled with putty or cement,"

Now when if it is thought necessaryybut I believe that" ordinarily it will not be necessary, that when first set up the joints will be tight, and that sufficient dust and soot will settle in them to IOO . formed in one piece.

substantially as shown. downwardly-bent edges of the opening in the with one another at the corners of the range by oblique external cup-j oints K, which stand at an angle of forty-five degrees, subst'ar'i tially, to both of the sides so joined. The bolts M, which fasten the joints, are therefore all outside, where they maybe easilymanipulated either in setting up or knocking down the stove. The bottom F of the stove is also united to the sides by cup-joiuts K, which form a downwardly-turned flange f, extending down from and all around the range upon which it rests, thereby holding the bottom from the floor.

The top G of the rangemay also be made of steel, and I may say here that I do not believe a steel top has ever before been used on a range. I am able to use such a top, and such top does not become warped from use, because of the peculiar construction thereof, as shown, and because of the form of joints by which it is secured in place. The top may be made of one piece or of'several pieces suitably connected. In it is formed an opening to receive the cover, center, or frame. The edges of this opening are bent downward, then inward, as shown, forming the seat g, on which the cover, frame, or center rests. This edge is again bent downward, and at the front and back (and at both ends, if desired) the said downwardly-bent part of the top is united with the top edges of the sides-that is to say, with the parts a and b, as shown by means of cup-joints and bolts,'substantially as shown in Figs. 2 and 5. edges of the top are also turned down to form a flange g, and the lower edge 9 of this flange is folded up inside and against the said flange, This flange and the top make the top rigid and, together with the described joints, prevent it from warping or bending.

In the preferred construction there are three oven-plates, which are secured to the front A and back 13 and to each other by cup-joints K and bolts In the preferred construction the tops and right side e are The bottom 6 is united to the right side 6 by a cup-joint K, formed by bending the lower edge of the side e to form a channel 7c, in which the downwardlybent edge of the bottom is secured by bolts W, as shown. The left side 6 is united to the bottom by cup-joint K, formed by bending the bottom plate so as to form a channel it, in which the lower edge of the plate a is secured by bolts 70 which bolts also connect the said oven -plates to a vertical wall J, which separates the ash-pit from the flue. The left oven-plate is connected to the top by a cup-joint formed by bending the upper edge of the plate a to form a channel 70', in which the upturned edge of the top plate 6 is secured bybolts 70 In the front A is formed the usual opening for the oven. The piece a preferably forms The outerthe top of thisopening. The edges of this opening are folded backand are united with the oven-plates e e e e by cup-joints which are fastened by bolts. It is not believed that it is necessary to describe specifically the manner in which each particular cup-joint is formed. The specific forms clearly shown in the drawings are not material and may be Varied as desired. I may say, however, that when formed as shown the parts may be assembled and connected in the described relation to one another. In like manner an opening is made in the back 13 of the range, and the edges of this opening are bent inward and are united with the oven-plates by cup-joints and bolts. A separate piece B, which forms the rear wall of the oven as well as a part of the back of the stove, may be connected in place in the same cup-joints by the same bolts.

An escape-flue II for the products of combustion is secured against the back of the stove by bolts which pass through the flanges and part B. The products of combustion pass over the oven, down between the oven and right end-of the range, beneath the oven, and then into the discharge-flue, which is formed as last explained.

The doors used to close the various openings may also be made of steel, and when so made their edges are folded over and then bent away, thus strengthening the doors and forming a tapered seat having just a little spring to it, which makes a tight joint with the openings said doors are designed to close.

From the foregoing description it will be seen that because the top parts of the side above the oven are bent outward the oven need not be as long substantially from back to front as the top is. Steel ranges may be built, therefore, with a small body and oven and a comparatively large top, substantially like cast-iron stoves, for example. This has not been possible before, so far as I am aware, with steel ranges. When they are so built, it is obvious that they will cost less than the prior steel ranges having like top capacity.

Another distinct advantage is this: The range may be easily set up by any one with .a screw-driver and wrench, wherefore they may be shipped knocked down at a great saving in freight.

Having described my invention, I claim* 1. In a steel range, in combination, the sides and a steel top having an opening for the cover-frame and having the edges thereof bent down and united to some of the sides by cup-joints and bolts, substantially as and for the purpose specified.

2. In a steel range, in combination, the sides having their upper portions bent outward, a steel top having an opening and having the edges of said opening bent down and.

. in to form a seat for the cover-frame, and

then down again, said last-named downwardly-bent parts being connected with the topsof the sides, substantially as and for the purpose specified.

3. In a steel range, in combination, .the front having an oven-opening, a piece a secured to the top of said side and forming the curved inward again, substantially as and for the purpose specified.

5; In a steel range, in combination, the sides, and a steel top having on its outer edge a downwardly-turned flange, the edge of which is folded up against said flanges, and havingan opening for the cover-frame, the edges of said opening being bent down again, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.

ADELBERT E. BRONSON.
